Because it is showy and offers accessible nectar, a great variety of insects visit the blue-weed; Muller alone observed sixty-seven species about it. We need no longer wonder at its fertility. Of the five stamens one remains in the tube, while the other four project and form a convenient alighting place for visitors, which necessarily dust their under sides with pollen as they enter; for the red anthers were already ripe when the flower opened. Then, however, the short, immature pistil was kept below. After the stamens have shed their pollen and there can be no longer danger of self-fertilization, it gradually elongates itself beyond the point occupied by them, and divides into two little horns whose stigmatic surfaces an incoming pollen-laden insect cannot well fail to strike against. Cross-pollination is so thoroughly secured in this case that the plant has completely lost the power of fertilizing itself. Unwelcome visitors like ants, which would pilfer nectar without rendering any useful service in return, are warded off by the bristly, hairy foliage. Several kinds of female bees seek the bugloss exclusively for food for their larvae as well as for themselves, sweeping up the abundant pollen with their abdominal brushes as they feast without effort. BLUE VERVAIN; WILD HYSSOP; SIMPLER'S JOY (Verbena hastala) Vervain family Flowers - Very small, purplish blue, in numerous slender, erect, compact spikes. Calyx 5-toothed; corolla tubular, unequally 5-lobed; 2 pairs of stamens; 1 pistil. Stem: 3 to 7 ft. high, rough, branched above, leafy, 4-sided. Leaves: Opposite, stemmed, lance-shaped, saw-edged, rough; lower ones lobed at base. Preferred Habitat - Moist meadows, roadsides, waste places. Flowering Season - June-September. Distribution - United States and Canada in almost every part. Seeds below, a circle of insignificant purple-blue flowers in the center, and buds at the top of the vervain's slender spires do not produce a striking effect, yet this common plant certainly does not lack beauty. John Burroughs, ever ready to say a kindly, appreciative word for any weed, speaks of its drooping, knotted threads, that "make a pretty etching upon the winter snow." Bees, the vervain's benefactors, are usually seen clinging to the blooming spikes, and apparently sleep on them. Borrowing the name of simpler's joy from its European sister, the flower has also appropriated much of the tradition and folk-lore centered about that plant which herb-gatherers, or simplers, truly delighted to see, since none was once more salable.
